320 AMERICAN HYMENOPTKRA. 



with this type, of specimens which I have sent him, I sent 

 him a nearly typical queen huntii, giving it the label number 

 " 33," and he writes, after pointing out slight differences 

 between this specimen and the rufosuffusus type, as follows : 

 "33 is, I think, really rufosiiffusjis ; whether a variation or 

 a geographical race cannot be determined without more 

 material." As huntii varies a little in most of the characters 

 pointed out, I have not the least doubt that the two species 

 are the same. 



Pile of medium length and rather coarse. Face and occiput yellow ; 

 thorax tnostly yellow, but with a black band between the wings with its 

 hind border nearly straight. Dorsum of abdomen with first and fourth 

 segm.ents yellow, second and third ferruginous-red, fifth and sixth black 

 {in the females). Females with legs dark and corbicular fringes black. 

 Malar space of m.ediutn length . 



Queen. Head. — Slightly elongate. Face largely covered with rather 

 dense yellow pile ; occiput with a large triangle of yellow pile ; cheeks 

 black. Labrum with tubercle-like areas large and well separated, 

 their summits rather strongly concaved and margins rather sharply 

 elevated ; space between these areas and above the shelf-like projec- 

 tion deeply excavated ; shelf-like projection rather narrow, but promi- 

 nent ; translucent spots usually plainly visible to the naked eye. Man- 

 dible, at most, with only a slight indication of a fourth tooth (resem- 

 bling ternarius in this respect). Malar space somewhat shorter than 

 its width at apex, about one-fifth as long as the eye. Clypeus coarsely 

 but rather sparsely punctate. Flagellum of antenna somewhat less 

 than twice as long as the scape ; third antennal segment much longer 

 than the fifth, the fifth somewhat longer than the fourth. 



Thorax. — Dorsum covered with yellow pile, except for a black band 

 between the bases of the wings, the hind margin of this band not ex- 

 tending back onto the scutellum in the middle ; mesopleura mostly 

 covered with yellow pile, but the yellow not reaching the bases of the 

 legs and often coming considerably short of it, sometimes nearly the 

 whole lower half black ; metapleura and sides of median segment often 

 bearing very little but dark pile, but often with nearly pure yellow 

 pile ; center of disc naked, smooth and shining. 



Abdom,en. — Dorsum : segment one yellow ; segments two and three 

 ferruginous-red ; segment four yellow ; segments five and six black. 

 Venter mostly black, but with the sides of the apical margins of some 

 of the middle segments fringed with yellow hairs, especially of seg- 

 ments three and four. 



Wings. — Rather strongly, but not deeply, stained with brown ; the 

 fore pair lightest across the middle and darkest in the median and sub-
